Natural selection may make it seem as if evolution moves in an "upward" direction, but this is not the case.
Quote:You should be able to pick out hundreds of these changes as there are multitudes of subsystems that are being altered. Where are of these mistakes?Those "mistakes" are probably more notable in the millions of species that no longer exist because they did not evolve the necessary mechanisms to survive ongoing changes in their environment or in competing organisms.
Evolution only seems to move "upward" because those species that don't evolve in a sufficiently beneficial direction die out and disappear. The creatures that populate the world today are the result of a sifting out of a heck of a lot of failures, many of which we find in the fossil record and many which we will probably never find out about. How does that point to an intelligent designer providing complete forms or evolutionary guidance?
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
